AVANTEKAdd-On Plug-in Receiver RB-1, 1300 Feet Range with 52 Chimes, Black

Item wasn't compatible as described.

Update: I contacted the seller who advised me I have an older version doorbell transmitter. He told me how to order the correct receiver which I did after returning the first one. The new one works fine. Just make sure you order the correct receiver for your transmitter. You may need to contact the seller to know which one to order. The seller gave me half off the price to compensate me for my trouble. I changed my rating from one star to five star because the second receiver works great.Receiver won't pair with the D-3B transmitter even though the product description says it does. Lots of reviewers had same problem. Company should not keep selling something that they know does not work.

Setup was simple and it just works. Battery is forecasted to last three years on the bell. We will see.

I bought this for my classroom so I don't have to raise my voice to get my students attention. Love this!

Seems to work as expected and required. It has loads of annoying 'tunes' so you are likely to stick to the basic 'ding dong' doorbell sounds. It's very easy (one button) to change the tune so tell your kids not to mess with it! I needed an extra receiver but really annoyingly they only do those in black, so I have two white and one black! Overall however, it works well and looks good.n.b. I'm on a mission to write genuine reviews (too many fake ones). I genuinely purchased this item with my own money without incentive or connection to the seller/manufacturer. If you find my review useful, please click 'helpful' so I know, thanks.
